Four years after then-commissioner Peter Ueberroth declared baseball to be drug-free, Fay Vincent says he isn't so certain.

At the start of the 1986 season, Ueberroth said drugs were "flat over . . . done." Vincent, the current occupant of the office, wishes he could be that certain.

"I worry about it," Vincent told a delegation of Associated Press sports editors yesterday in New York. "I don't know the extent to which they exist in baseball. Is it 1 percent or 20 percent? There's no way to know and I can't find out."

Vincent said he believes most players would support a drug-testing program. "Nobody wants the circumstance to be ignored," the commissioner said. "We've talked to the union about the extent of the problem. Nobody knows. But any statement that baseball is free of drugs can't be supported. I believe there is a problem. I don't know how great it is."

On television broadcasts: "It's easy for Congress to say it is on the side of more baseball on television. Life is not that simple. Congress doesn't deal terrifically well with facts."

On his job: "I wonder is it always one crisis after another? First, there was the {Pete} Rose thing. Then Bart {Giamatti} died and that was a terrific trauma. The earthquake at the World Series. Labor. Steinbrenner. Expansion. Given the complexity of American life, the role of baseball and its visibility, this position is one major go after another. It's as good a way as one can spend his time. What I really enjoy is I get paid to go to ball games. I'm going to six games next week, a baseball orgy. And nobody sits in front of me."
